4. The computer system according to claim 1 , wherein the computer system is operative to register instructions to alter the list of words associated with any of the letters, and upon receiving such instructions to alter the list of words accordingly.

5. The computer system according to claim 1 , wherein each of the word lists is associated with a name, the names being editable.

6. A computer system having a computer and a keyboard, the keyboard having a plurality of pairs of keys, each pair of keys comprising a first letter key and a respective second letter key, each pair of keys being associated with a single respective letter such that the first letter key and the second letter key of each respective pair together form a respective, otherwise regular key, on the keyboard; the computer system being arranged such that: (i) upon activation of one of the first letter keys, to register the selection of a corresponding single letter, whereby a user can type a text by consecutively striking once the first letter keys corresponding to consecutive letters of the text; and (ii) upon activation of one of the second letter keys, a user is presented with a predefined list of one or more words, the words of each list beginning with the corresponding single letter, the computer system being arranged to register a selection by enabling the user to select one of the presented words; wherein, for each pair of keys, the first letter key neighbors the second letter key such that each of the first letter keys is immediately adjacent the second letter key, with no intervening keys.

7. The computer system according to claim 6 , wherein the second letter keys can be deactivated.

8. The computer system according to claim 6 , wherein at least some of the letters are associated with a corresponding plurality of word lists, each word of each word list being associated with the corresponding single letter, the computer system being arranged upon activation of one of the second letter keys, to register at least one command indicating a selection of one of the word lists associated with that letter, and to present the user with the selected word list, whereby the user can make a selection from the selected word list.

9. The computer system according to claim 6 , wherein the computer system is operative to register instructions to alter the list of words associated with any of the letters, and upon receiving such instructions to alter the list of words accordingly.
